Wong call at very wrong time

Dear friends,
If a call comes in the middle of sleep at midnight then definitely it will be scaring.
Yesterday my mobile rang at 2.30 am. I woke up on hearing the sound as I could not understand what the sound is. On waking up from sleep I realized my mobile rings. I picked and kept on my ear without saying anything as it was from an unknown number. The call got disconnected but the next minute it rings again. This time I pick and said a ‘hello’. The person on the other end said to me, “Sorry wrong number”. Imagine, someone wakes me up from sleep and saying this.
Some aged person was on line and may be on emergency he called up some one and he got a wrong number that is what I felt on that time. I didn’t felt annoyed or anything, I kept the phone back and slept again.
Do you get calls at wrong time, especially wrong numbers?

Wrong number at that time. Lol, that's really freaking.
Honestly just got call at 12:30 am yesterday when I was trying to sleep. I got scare (it is always scary to get calls at that time). It was my dad and I got even more scared. But it was only for checking out water at terrace as it was heavily raining at night. Thank god.
